@article{23891, abstract = {{Within a pre-post-design, we scrutinized the effects of normative augmented feedback with positive and negative valence on learning motor accuracy, consistency as well as automaticity by means of a dual-task paradigm. Forty-two healthy physical education students were instructed to produce an arm-movement sequence as precisely as possible with regard to three spatial reversal points within a time limit of 1200 ms. Twenty-eight practiced an elbow-extension-flexion-sequence (690 trials) and 14 participants were tested as a control group without feedback practice. Valence of normative feedback was systematically manipulated by means of reference lines in a visual feedback display. The reference lines indicated performance of a putative peer-group either to be superior (negative valence, Normative-Negative-Group) or inferior (positive valence, Normative-Positive-Group) to participants’ actual performance. As a result, dual-task costs (n-back error) significantly decreased solely in the Normative-Positive-Group, p = .003, η2p = .51, but in no other group. Surprisingly, the mean absolute error for the motor task significantly decreased (i.e., precision increased) only in the Normative-Negative-Group with a large effect size, but in none of the other groups. Motor consistency was not significantly affected by the valence of normative feedback. According to the hypotheses of error-provoked attentional control, positive feedback-valence appears to enhance skill automatization, while – unexpectedly – only negative feedback-valence seems to enhance movement precision, which may be explained by effects of feedback valence on the learners aspiration level.}}, author = {{Zobe, Christina and Krause, Daniel and Blischke, Klaus}}, journal = {{Human Movement Science}}, keywords = {{Augmented feedback Automaticity Dual task Motor learning}}, pages = {{529--540}}, publisher = {{Elsevier}}, title = {{{Dissociative effects of normative feedback on motor automaticity and motor accuracy in learning an arm movement sequence}}}, doi = {{https://doi.org/10.1016/j.humov.2019.06.004}}, volume = {{66}}, year = {{2019}}, } @article{48703, author = {{Zobe, Christina and Krause, Daniel and Blischke, Klaus}}, issn = {{0167-9457}}, journal = {{Human Movement Science}}, keywords = {{Experimental and Cognitive Psychology, Orthopedics and Sports Medicine, General Medicine, Biophysics}}, pages = {{529--540}}, publisher = {{Elsevier BV}}, title = {{{Dissociative effects of normative feedback on motor automaticity and motor accuracy in learning an arm movement sequence}}}, doi = {{10.1016/j.humov.2019.06.004}}, volume = {{66}}, year = {{2019}}, } @unpublished{16711, abstract = {{Embedding techniques allow the approximations of finite dimensional attractors and manifolds of infinite dimensional dynamical systems via subdivision and continuation methods.

The idea sounds simple and convincing: cut out the corporate middleman and replace Uber with a service owned and managed by taxi drivers themselves, create a version of Airbnb run by cities, or turn Facebook into a platform democratically controlled by all users. This article discusses the ambivalences of platform cooperativism, exploring both the movement’s potentials to subvert digital capitalism from the inside and the risk of being co-opted by it. Platform cooperativism aims to foster social change by creating a People’s Internet and replacing corporate-owned platforms with user-owned co-operatives. It yokes social activism with business enterprise. As a result, the movement is shaped by tensions and contradiction between politics and enterprise, democracy and the market, commons and commercialisation, activism and entrepreneurship. This article explores these tensions based on a Marxist perspective on the corrosive powers of capitalist competition on the one hand and a Foucaultian critique of entrepreneurialism on the other. It concludes with a reflection on the politics of platform cooperativism, drawing out problematic implications of an uncritical embrace of entrepreneurialism and highlighting the need to defend a politics of social solidarity, equality and public goods. }}, author = {{Sandoval, Marisol}}, issn = {{0896-9205}}, journal = {{Critical Sociology}}, number = {{6}}, pages = {{801--817}}, publisher = {{SAGE Publications}}, title = {{{Entrepreneurial Activism?
